Man, nested mask groups changed my whole workflow too! I picked it up from a random YouTube short last year where the guy put each body part in its own folder before masking, so when I clip a shadow it only grabs that one section and my lines stay safe. My layers got way more organized after that since I'm basically forced to sort stuff as I go. Still keep a flat copy at the end just in case something weird happens though.

Man, that PVC gutter trick is the part people sleep on. Everyone fixates on the framing and the slope, but moving water where you want it is what keeps a structure from rotting out in five years. The real genius in setups like that is the whole thing works with gravity and junk you already have lying around, no pumps, no wiring, no fuss. What gets me is how much of this stuff used to be common knowledge that just died out when everyone started buying prebuilt. My grandpa had a smokehouse with a rain catch that ran on the same idea and nobody wrote it down anywhere. That farm stand basically preserved a free blueprint that a hundred guys with fancy sheds have never once thought about.
